T all whom/z5 may concern: j

Be it'known that I, FRANK DIEHL, a citizen of the United States,residing at Sheboygan, in the county of Sheboygan' and StateofWisconsin, have invented a new and useful Planer Attachment, of whichthe following is a specitremity opposite the attached end/thereof,`

controlling mechanism includinga counterpoise, the device being adaptedfori use vwith p one or more planers' below the same or above 2o thelevel thereof. l

Other objects and advantages will appear in the subjoined disclosure ofthe structural features of the invention and the novelty will behereinafter claimed, a preferred embodiment of the invention beingillustrated in the accompanying drawings, wherein#- Figure 1 is adiagrammatic view in sectional elevation illustrating a number' ofplauers at different elevations and the improved jack in side elevation.Fig. 2 is a top'plan view of the improved jack, showing hangers for aApart thereof in section. Fig. 3 is a transverse vertical sectionthrough the controlling mechanism. Fig. 4 is a longitudinal sectionthrough the controlling mechanism. A

Similar numerals of reference are employed to indicate correspondingparts in the several j views. f

The numeral 1 designates a line-shaft, to which the jack 2 is movablyfastened by boxes 3. The jack hangs horizontally in a plane at rightangles to the said line-shaft 1 and is automatically adjustable aboveand below said plane and controlled by mechanism which will be presentlydescribed. On the line-shaft, between the boxes 3, is a driving-pulley4, adapted to be traversed by a belt 5, which runs to a receiving-pulley6, fixed on a jack-shaft 7, mounted in boxes 8 on the outer extremity ofthe jack-frame 9. The motion of the shaft7 is transmitted te differentpoints by means of one or more pulleys 10, traversed by suitable obviousthat a number couldbe used or a compound pulley capable of receiving anumber belts, as 11, which are crossed V te obtain the j` proper.direction of rotation, and although of belts might also lbe employed.These vare l l mechanical substitutions well understood in the art ofpulleys and shafting and have not been specically disclosed in thedrawings for l this reason.

The jack-frame` 9 comprises opposite side bars12, having their rearextremitiesconnected to the boxes 3 andat thefront are made continuousbyineans of a yoke 13. yThe side bars 12 preferably converge from'thebox y toward the yoke 13, and adjacent vthe box 8 vvertical openings 14are formed in the said side bars 12 .tol receive oppositely-disposedsafety-rods 15, which are hung fromthe flooring above orv any othersuitable support and have their lower` extremities threaded to re- ,l

pressed without bindingand an adjustment can be `acquiredby moving'rthenuts 17 on the screw-threaded extremities-16, aswill be read# ilyapparent.v -The purpose of. these safetyrods is toprevent the jack fromfalling in the event of disconnection of the boxes 3 or breakage oftheframe, and thus avoid serious yconsequences to workmen below should suchseverance take place. y

To the .central part of the yoke 13a pair of links 18 are pivotallyconnected and at their j points of 'attachment embrace a lug 19. vTheupper endsof the links are movably secured n 13o-the arm20 of abell-crank lever 21, which is fulcrurned on a rock-shaft 22, journaledat opposite extremities in the lower portions of a pair of hangers 23,also dependingfrom-the ioor above and adjacent which are another pair ofhangers 24 to provide a'bearing for a second rock-shaft 25 in theirlower extremities, on which is iixed a bell-crank lever 26. The arm 2Oof the bell-crank lever 2l, to which the links 18 are connected, extendsin the direction of the jack, and the arm 27 of Ysaid bell-crank leveris connected to the upper arm 28 of the bell-crank lever 26 by aconnecting-rod-29.. To the other arm 30 of the bell-crank lever 26 acounterpoise-weight 31 IOO 2l being longer than the arm 28 of thebellcrank lever 2G it is necessary to locate the shaft 22 in a planebelow thatof the shaft 25 in order to'have the connecting-rod 29 Vworkin awhorizontal plane, 'which is essential in view of the fact that thereverse arrangement of the bell-crank lever increases the sensitivenessof the'controlling mechanism and establishes a compensatory combinationof elements that will conjointly. work in a practical manner to attainthe desired result.

From an observation of the showing in Fig, 1 it will be seen that theplaners can be belted either up or down or at any angle desired. Whenupper planers are belted to thc jack,

the` counter-poise or weight 3l must be lighter than whenthe jack isbelted to a planer bcneath the same, and it isobvio'us that'the beltswill be run through the flooring when the planers are above the jaclgandsuch other appliances as may be necessary will be used andef-a form wellknown 'in the art to assist inthe direction of the belts.

runs downwardly to the planer-cylinder 33,

and insome instances it will be preferred io have the said cylinderdirectly under the jack, as in the particular one of the planerswhichhas been referred to. In all the arrangements the jack worksautomatically through the medium of the counterpoise or weight 3l, and,againrreferring to the planer 32,when the planer-bed is loweredthe jackswings' downwardly with the strain of the belt 1l at an angle tothe saidplaner and a distance corresponding with the adjustment of thebed.

This downward movement of the jack is exerted against the resistance ofthe counterpoise or weightl, and when the planer-bed is raised toitshighest point the said counterpoise or weight raises the jack. Theother planers shown below the jack on opposite sides of the planer 32will also produce a similar movement of the jack when their beds areraised or lowered, as well as the planer shown overhead or above thejack, wherein, for instance, the planer-cylinder is up, and theadjustment of the bed in a similar direction will raise the jack againstthe resistance of the weight 31, and a depression of the bed of thisReferring now more particularly to the under planer, (desig-y nated 32,)it willbe observed that the belt 11 planer will allow the jack to returntol its normal horizontal position. This same adjustable characteristicof the jack is followed out uniformly in the several arrangements of theplaners, and the weight 3l is varied to suit different arrangements, andparticularly in connection with the overhead planer, as beforeindicated. y

Having thus-described the invention, what is claimed as new isp l. Thecombination with a power-shaft, of an automatically-adjustable jackmounted thereon and disposed in a normal horizontal position, said jackincluding in its organization a shaft at its extremity farthest from thepower-shaft and having motion transmitted thereto from the saidlpower-shaft, andadapted to be taken therefrom to other mechanism, andweight-controlled levers movably connected to the extremity of `the jackhaving i the motion-receiving shaft therein.

The combination with a line-shaft having a' driving-pulley thereon,of a horizontally-disposed jack movably attached to the said shaft andsupporting a shaftwith power receiving and conveying pulleys inconnection therewith, the power-receiving pulleys having motion impartedthereto from the driving-pulley-on the line-shaft, a counterof the jackopposite that attached tothe lineshaft and suspending' devicesadjustably attached to the extremity of the jack to which thecounterpoise mechanism is connected.
